77o oZZ whom t may concern: Be it known that l, EDWARD CRAIG, s. citizenof the United States of America, ond resident -of St. Joseph, Berriencounty, Michigan, have in vented o. certain n eW and useful Imprm'enientin Metul-Bound-BOX- End-Stnpling Machines, oi'- which the following,r isa specification. 'My invention relzites to machinery for making boxes orother like receptacles. It contemplates broadly a machine that willstaple the ends of a metelbound box, by inserting the staples throughthe sheet metal binding z l'rid into the end Walls oflthe box, thussecuring the end' walls and sides of the box together.

Prior to my invention, it was not possible to staple the ends ot' u. boxof this particular character, :is it was not known, until demonstratedby me, that wire staples could be driven through the metal binding of'this box. l

It is also un object, of course, to provide certain details und featuresofi construction and combinations tending to increase the generalefiiciency anddesirability of a. metal-bound'boxenrhstapler of thisparticular character.

' In theaccompairying drewings-Figure 1 is s side elevation of :i metalbound box end stzipling m'uchine embodying vthe* principles of myinvention. Fig. 2 is s detail plan view, on :i larger scale, of the endportion on line Ill-11 in Fig. 10..' l.

upon the upper ends of which are rigidly 'mounted the"laterally andsubstantially horizontally projecting firms B :ind C, whereby thevarious operative elements are supported in suitably elevated positions.A horizontal shaft ll) extends longitudinally withingthe arm Bend is,provided at its outer end with'a driving' pulley ai which is governed bya. clutch ci controlled by a. foot lever el in the usuel and Well knownmanner;

The stapling head E is mounted in an upright manner at the outer endofthe :trxn. B, and comprises the well known staple former .e, the usualstaple driver c', and the loo bnr e", together with a lock ef forautomaticully locking and 4unlocking the" .staple former, allconstructed and operated'in the welll known manner. rI he staple drivere bnr,- which latter is pivoted at e9 and con trolle'd lby the 'com @1.0on the back of the' staple driver. A linke11 is pivoted on the upper endof the staple former e, and provided :1t-its lower end with, a fingerel?, which lutter is adopted to be inserted loetween the pointsof thestaple, when the latter strikes the sheet metal binding, as willhereinafter more fully appear. A rod eli has its lower-endfpivotcd tothe link e, and has its upper end held for vertical reeipr'ocntioninthe' 'guide plate e, 'which laitter is securedfto-the verticllyreciprocating heed e. The rod e has a. 'collar-e, and a spring el? isinterposed: between this coller'` and-the bottom of the plate e, wherebyspring pressure vis always exerted downward upon the staple former e.The lock c is pivoted on the staple driver, and. e cam ci" is providedon the casing of the stapler to engagev the said lock at the propertimeand thereby disengagc it from the staple former,

thus permittingihe staple driver to continue its downward movement afterthe `staple former `engnrg'es the surface of the sheet metal.'

,is secured to oneside of the vertically recip-- binding through whichtho staple is to be inserted. 'lhtshort length of wire is bent upon theloop bnr of. by tho downward' movement of thu .xlottrd or hifnrrntedstaple former r, in the nxuul innnnur.

When the ituple is fully l'ornied. the stnplo former engngrx thosurfnceol' thel short nietnl binding, und ut thel Snmr timv thvv lingrr eenters the. slot a in the fare or cover plnte e10 of the stapler.

Then the pirated lotlt e strikesthe Ginn n". thus unlorlting the, staple former, and prrmitting thestaple driver to continue its .lownwzird movement alone. 1n this way thestnple, is inserted through the metal binding ot' the box, :is shown inFigs. 4, 5 und t3, and when the top of the staple strikes the beveled orrounded end of the-linger rr, the lutter is thereby thrown outward t0permit ithe complete insertion of the staple. The wire i'or tho staplesis carried onu wel I", und is fed through al feed tube f neir thobottoni of .the stapler head.
